The wasted time is caused by the use of too rigid incorrect tubing such as water hose used for pumps and pools ,there are a
lot of incorrect assumptions made from short cuts tried and the differences used with negative pressure versus positive ,
blower, fans bellows .fish pumps ,hair dryers ,There are a lot of differences with using plumbing fitting Y's ,tees and bulky ,contraptions ,expensive filter blowers ,fenwal couplings ,bulky ,funnel adaptors octopus arrangements and lack of cfm .
distances from dust sources ,reguardless ,of actual effeciencies and actual amount of actual dust collected and piping rat
nests created ,blocking use ,saw and area around saw , I suppose some feel the limited benefits are worth these limitations
while still having to use ,filters fans and still having to use masks and still having dust all over are worth the expense andplumbing nightmares . I have yet to hear any say any are (Dust Free) ! The combination of the wrong stuff took a long time to
work out ,some will never be satisfied ,some are easily satisfied and still have a mess on and all around their saw ,some are happy with just the blower and all the dust , all you have to do is look at the pictures to see which is which , wasted time
comments from the the dustiest and cluttered shops are remarkable . Please don't scoff till You actually have some thing that is (Dust free) and is user friendly .Well that's my rant for the day ,Peace and fun for everyone !
